Seraphim is created from prototypes of the Seven Storm Dragons, possessing tremendous power.
A new revelation about Seraphim is presented in chapter 1090 that is truly astonishing. They were captured and confined in energy-transmitting sea stone bubbles.
In the One Piece manga, the World Government has unveiled their new weapon - the Seraphim. Seraphim are combat cyborgs created by Vegapunk. They are the new generation Pacifistas with superior strength and combat abilities compared to the old generation.

The interesting thing about these Seraphim is that they are copies of the Seven Warlords. In terms of appearance, they resemble children with white hair, dark skin, black wings, and a spot of fire. These new generation combat cyborgs possess both Devil Fruit powers and the resilience of King's Lunarian race. S-Snake, a copy of Boa Hancock, who has the ability to turn things into stone, has proven to be formidable.
Seraphim has been seeking ways to engage and challenge the main characters in the storyline, including Luffy, Zoro, and Lucci.

The unique personalities of each Seraphim are inherited from their original prototypes. And these standout traits may be the biggest weakness of Seraphim, something seemingly unforeseen by both Dr. Vegapunk and the Five Elders.
Luffy, with his direct and straightforward approach, managed to free his friends turned to stone by S-Snake by exploiting the clone's emotional sensitivity.
This inadvertently raises critical questions about controlling these new weapons. Especially considering that other renowned Seraphim clones are derived from Hawkeye, Jimbe, Kuma, Crocodile, Gecko Moria, and Donquixote Doflamingo.
The prospect of a particularly formidable 'mini' Doflamingo poses a potential threat to the world of One Piece. The unpredictable nature of Seraphim's personalities could become a bigger issue for the World Government than the original Seven Warlords.

According to current predictions, the number of Seraphim will correspond to the characters who were once the Seven Warlords. In One Piece, a total of 11 Seven Warlords have been introduced, so there might be 11 Seraphim.
The question now is whether the personalities of Seraphim will become exploitable weaknesses in the future, as Luffy did with S-Snake. The upcoming chapters will shed more light on this intriguing theme.
